Spoke cav­i­ties have been de­vel­oped and have ap­par­ent ad­van­tages for high cur­rent pro­ton ac­cel­er­a­tor based on su­per­con­duc­tiv­i­ty at low and medi­um en­er­gy re­gion. As the re­search and the tech­ni­cal re­serve, Peking Uni­ver­si­ty has start­ed the R&D pro­gram of sin­gle spoke cav­i­ty (SSC). The work is pro­posed to do beam load ex­per­i­ment on the HI-13 Tan­dem at CIAE. The max­i­mum ki­net­ic en­er­gy of pro­ton beam is 26MeV, and the fre­quen­cy of the chop­per for su­per­con­duct­ing is 150MHz. It leads us to the choice of a 450MHz and β=0.2 sin­gle spoke cav­i­ty. In this paper, the RF de­sign, me­chan­i­cal study, fab­ri­ca­tion arts, tol­er­ance anal­y­sis, and room tem­per­a­ture RF test is pre­sent­ed.
